Resume frame callback on host resume

[s77rt]

Summary:

When the app goes into background the frame callback is ignored by setting the mShouldStop flag to true

react-native/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/uimanager/events/FabricEventDispatcher.java

Line 174 in 3111473

mCurrentFrameCallback.stop();

However this flag is never reset even after the app is back on foreground. This made the AndroidEventBeat not ticking in as much as expected causing events not being dispatched in time. In our case the onLayout was not being dispatched unless we tap on screen invoking a manual tick.

Changelog:

[ANDROID] [FIXED] - Fix Frame Callback not being called after Host Resume

Test Plan:

1. Add log line __android_log_print(ANDROID_LOG_DEBUG, "s77rt", "AndroidEventBeat::tick"); in packages/react-native/ReactAndroid/src/main/jni/react/fabric/AndroidEventBeat.cpp (tick method)
2. Open RN-Tester
3. Verify AndroidEventBeat::tick is logged for every frame
4. Put app into background
5. Verify no AndroidEventBeat::tick is logged
6. Open app again
7. Verify AndroidEventBeat::tick is logged for every frame
